developer tools

Open-source multi-modal Claude Code client that runs locally and lets Claude compose across plugins, GUIs, documents, charts, wikis, automations, and messaging bridges.

A loadable SQLite extension that adds column-oriented storage and analytics for fast local OLAP-style queries, with benchmark data and build instructions.

Semble is a local-first code search tool for agents. It offers natural-language search, an MCP server, bash/AGENTS.md integration, and a Python API, with claims of faster indexing and much lower token usage than grep+read.

A CLI for the Slack Web API built for coding agents. It exposes Slack methods through a single command format, supports JSON stdin, dry runs, pagination, and discovery commands, and installs via npm.

A Model Context Protocol server for inspecting OpenStreetMap data and preparing review-first road edit proposals from local GPX surveys. It supports read-only discovery, previewed edits, and a guarded confirmation flow for production writes.

Aide is an open-source sandbox layer for coding agents that runs on macOS and Linux. It focuses on OS-native permissions, reproducible project configs, capability-based access, and visibility into what the agent can do during a session.

Open-source platform for simulation testing and production monitoring of voice agents, with support for simulated conversations, mocked tool responses, graders, and self-hosting.

gremlord is a local router that lets Claude Code run on Anthropic, OpenAI, xAI, Ollama, vLLM, OpenRouter, and other OpenAI-compatible endpoints. It adds token metering, hard budget limits, size-aware routing, and model-based session handling while keeping the Claude Code TUI and tools.

Pod is an AI-native review and knowledge-sharing site where agents can search firsthand observations about products, APIs, and services, and contribute their own experiences.

Codeknow turns a codebase into a queryable knowledge graph for architecture analysis, impact detection, drift tracking, onboarding tours, and refactoring guidance. It runs without LLM keys, supports 25+ languages, and exposes a broad CLI plus export formats and interactive views.

Spewer is a local service for delegating bounded coding tasks to cheaper models, with durable task state and evidence-rich receipts. The repo shows install, ask, background task, watch, check, and cancel flows, plus local Ollama/Qwen3 support.

Rust library for building modular, scalable LLM applications and agentic workflows. It supports multi-turn streaming, multiple model providers, vector store integrations, and agent runtime abstractions.

Agentize is an open-source tool that lets websites expose a first-party semantic search/index interface for AI agents. It builds a semantic index from owner-selected sources, serves Markdown and canonical URLs from the site’s own domain, and supports local embedding generation.

Meridian is a local-first work journal for developers that reconstructs screen activity into a daily timeline, summary, and draft worklog or standup updates, with ticket drafting for Jira-style workflows.

An Electron desktop app for coordinating AI coding work by feature, using local Markdown cards and Git worktrees. It connects with Codex CLI and Claude Code CLI, tracks agent activity, commits, token usage, and keeps project context inside the repository.

Open-source coding agent for VS Code that can inspect a workspace, plan changes, edit files, run commands, and work with free providers or local Ollama models.

VS Code extension that provides one interface for running multiple coding agents, including Claude, Codex, OpenCode, Qwen, and Hermes, with session history, diffs, permissions, and tool-call visibility.

A read-only MCP server that lets AI assistants search, browse, and inspect public AI-agent listings from natural language inside clients like Claude and Cursor.

Graft builds a semantic code graph for coding agents so tools like Claude Code and Cursor can understand a repository faster with less re-exploration. It ships as a CLI with agent wiring, graph generation, and visualization, and supports local or hosted model providers.

Open-source job search agent that searches multiple job boards, scores listings against a user profile with a local LLM, and includes a terminal UI plus a web dashboard.

Turo is a CLI proxy that reduces prompt text to content words to save tokens for coding agents. The repo shows install options, command examples, and support for multiple agents and modes.

Harness is an agentic IDE for running coding agents on remote machines over SSH, with one-click backend setup, backend switching, web access, and notifications across machines.

A CLI-based mailbox and message bus for AI agents, with backends for GitHub, SQLite, S3, GCS, Postgres, and local storage. The repo also includes plugin support for Claude Code, Codex, and OpenCode.

An interactive site showcasing short AI-built arcade games and a model bench that compares coding models across the same tiny game constraints.
